My invention has for its objects the prof.` vision of a simple, eiiioient oiler which shall feed only such lubricant to the springs es is necessary, thereby preventing Weste and ob' rioting the frequent refilling o'i the rubrioating devices; the provision of securing ineens which will hold the device in posi tion unelieeted-by the relative movement ot the leaves oi the spring while allowing ready attachment end removal; and the nrrangenient or the device so that it may oe lcheaply monili: etured and may have a neat and pleasing uppeurince when in position i'or use.

lily invention is hereinafter more 4ully described in eonneetion with the drawings, and the essential characteristics are set Jortli in the claims.

Referring to the drawings by reference nuinerels,l0 indicatesy n common forni oi2 lest spring used on vehicles, suoli es automobiles and the like; l2 indicates in Y lubrieatingdevice mounted thereon.

The device comprises n reservoir 14 adepted to stond adjacent the lower portion ot the top end bottom, and having on opening ooirniunieating with an upwardly extending conduit l5. This conduit extends over the leaves of the spring, and has an open side, closed by the edges of the leaves. The reservoir le preferably extends below the lower lest and under the some, providing a. shoulder, as at 16. Extending downwardly from the inner side of the reservoir is protided a. prog'ecting ear 17, approximately uishopeth adapted to receive the eye 18 of a spring 20. rlhe upper portion duit l5 is closed by atop member 22 extending over the upper leef and turned upwardly, forming an eer 23, also substantielly T-shaped, adapted to have its shank embraced by e similar eye 18 oi another spring 2G.

bis shown in Fig. 2, the reservoir extends upwardly pest soine of the lower leaves, having in its top 25, en opening adapted to be closed by e. plug 26. This plug comprises a split Sheng, the lower end of which is adapted to spread to hold the plug in position, and is preferably made integral w ith' a suitthe sides of o the conl able knob adopted to be grasped by the nl gers, for removal.

ln order to prevent the lubricant (which is usually en oil) within the reservoir, from leaking past the lower leaves of the spring, and thns being wasted, the portion forming the shoulder 16 is extended upwardly as at 28, overlapping a portion of the lower leaf, and within the reservoir l have provided a downwardly extending partition 29 between the sides ot the reservoir and having its lower edge extending below the portion 28.

Aecordingly, any oil escaping from the reservoir ninst flow upwardly betweenthe y portions 28 and 29. The conduit 15 is preferably lilled with e. suitable wick 30, extending from the top of the some substantially to the bottoni of the reservoir and tightly lilling the opening between the portions 16 and 28. l

lt will be seen that while there is anyoil in the reservoir it will iow upwardly along the wick, and that it will worlr its Way between the leeres or' the spring :is it is needed, thereby constantly lubricating the spring, but by reason of the action of the wick, it will not ilow tast enough to cause l waste of the lubricant.

it is frequently desirable to arrange these devices in pairs as shown in Figs. 2 to 4, and

they may be conveniently held in position by pairso springs extending between the i form of eyelets adapted to receive the `hooked end of springs 38', to hold these dewith springs yieldingly shifted along the leaf movement of the Vleaves projecting ears v17 drawing each lubricating `device tightly against the sides of Vthe .without danger of the devices shifting and 4The use'of these springs, however, securely holds them in this position, while allowing for ready removal and replacement when desired'. l

In the form shownin F ig.'4, the reservoir 32 corresponding to the reservoir 14 stands below the spring, and the top 33 of the reservoir is substantially on the' levelV withor slightly below. the lower edge ofthe lower leaf. The upper side vof the reservoir communicates Awith theopen sided rconduit l5,

the same 'as in the form described. lVith this construction, even when thelreservoir is full, there is no tendency for oil to vflow upwardly through the opening except through the capillary action of thel wick 30. AcL

cordingly, the lubricant will not be wasted.

The inner side 340i the reservoir 32, stands beneath the lowerfleaf, as shown, and the upper edge of thisfside abuts this leaf, while lthe top 35 of the conduit member is extended over the upperV leaf and turned upwardly, the same as in the form described. Except in this`fgure and in Fig. 5, the ears 36 corresponding to the projections 17, are in the vices in position, as -des'cribed.

It issometimes desirable to provide only one of. the lubricating devices at a given pof sition on the spring. In such a case, I prefer Ato use a single coil spring 40, illustrated on the oiling device in substantially the saine` in Figf, extending around the', opposite side of the'spring 10 and having its hooked ends 42 engaging hooked projections 44, formed position as theproj'ection's 17 and 36, heretofore described.

s It will be seen that by myinvention I have provided a very simple lubricator for leaf springs adapted to use oil and similar lubricants', Ncontained in a reservoir from which 1t cannot leakand be wasted, but from which it ',i s regularly and automatically fed to the 'sprin'g as required. The reservoir may be refilled by merely removing the plug 26, and

the oilers may be readily mounted inposition on thefspringsf'or removed by'merely fastening and unfastening the securing vto be lubricated, and a wick said reservoir through the opening leading to. the conduityand extending 4upwardly along the conduitfacross said lea-ves.
